Update from Met Office Adviser:
Outbreaks of light snow this morning and into the afternoon may lead to accumulations of 1-3 cm in places, possibly a little more on higher ground, before it clears to the north. It remains bitterly cold with temperatures remaining below freezing throughout the day and feeling well below freezing in a strong to gale force easterly wind. Areas of locally heavy snow is expected to develop and move north during the afternoon and evening although Oxfordshire is right on the eastern edge of this area. This area clears soon after midnight by which time we could have seen 2-5 cm quite widely but possibly as much as 5-10 cm on higher ground such as the Cotswolds. A Yellow snow warning is out covering the possible impacts from the snow today but the Amber warning has been removed from Oxfordshire. It will be very cold overnight with a severe frost before a further band of snow is expected to move north tomorrow morning bringing further fairly small accumulations (1-3 cm?) although there is some uncertainty around this band of snow and how much snow to expect. The wind will gradually ease but it will remain very cold. Looking further ahead it looks like it will slowly warm a little with a band of rain, possibly sleet, pushing north on Saturday night with the unsettled theme continuing into next week giving rain at times.
